Description
Technical field
The present invention relates to a kind of steel structure bridge sheet panel top element solder deformation correcting device and method, belong to steel structural bridge
Beam fabricates field.It is mainly used for steel box-girder and the correction of steel truss girder field thin plate of bridge floor plate structure.
Background technology
The main deck structure of steel structure bridge all uses floorings, when the thickness of slab of Slab element is not less than 12mm, at present
Machinery correction or（With）The method correction angular deformation that flame straightening combines, rippled edge shape is relatively small basic without correction, puts down
Face degree substantially disclosure satisfy that requirement.
But when the thickness of slab of Slab element is less than 12mm, such as tuyere Slab element of steel box-girder, steel truss girder etc., postwelding can produce
Raw complicated, big angular deformation and rippled edge shape, correction difficulty is quite big, and the thinner rippled edge shape of thickness of slab is more difficult to correct.Although angle
The enough mechanical orthosis corrections of deformation energy, flame straightening can then aggravate rippled edge shape.Rippled edge shape can only use flame straightening, fire
Flame correction damages greatly thin plate Slab element, and flatness does not reach requirement at all.
Either slab units or thin-plate element, a variant part can only be corrected every time at present by using during mechanical checkout
Position.Although flame straightening can also correct angular deformation and rippled edge shape, CO can be caused2It is a large amount of to be discharged into air, and work
Condition is poor.Both of which efficiency is low.
In addition the antidote of current Slab element, it is impossible to the residual stress of Slab element structure is eliminated, can be because stress be released
Put and be deformed again.
In order to mitigate weight, increase bridge beauty and resistance to corrosion, general steel plate is led to non-ferrous metal in bridge structure
Domain extends, such as aluminium alloy, magnesium alloy.Since thermal conductivity is good, flame straightening can not be implemented this metal.Machinery correction is only
One effective method.This just ties antidote and proposes new requirement.
The content of the invention
The technical problems to be solved by the invention be for the above-mentioned prior art provide a kind of angular deformation by Slab element and
The steel structure bridge sheet panel top element solder deformation correcting device and method that wave transformation is synchronous, is carried out at the same time.
Technical solution is used by the present invention solves the above problems：A kind of steel structure bridge sheet panel top element solder deformation
Apparatus for correcting, described device include leading with the fetalism of Components Matching, correct roller, roll-in force adjusting device, driving motor and operation
To device；
It is described with the fetalism of Components Matching on offer some notches, width of rebate is bigger 3-5mm than Slab element rib thickness of putting more energy into, excellent
4mm is elected as, for placing Slab element to be corrected；
The correct roller is arranged at the top with the fetalism of Components Matching, and roll-in force adjusting device, institute are set on the correct roller
Driving motor driving correct roller shaft is stated to rotate；
Running guiding device is connected in the shaft of correct roller both sides.
The clump weight of the roll-in force adjusting device by stent and thereon is formed, and the stent is by biside plate and top plate structure
Into biside plate is respectively arranged in the shaft of correct roller both sides, and the clump weight is arranged on top plate.
The top plate both sides set centrally-mounted driving respectively.
The running guiding device is arranged at stent biside plate outer lower portion.
The running guiding device is made of guide base and roll wheel assembly, and the guide base has two, two guiding
Pedestal is oppositely arranged to be fixed on side plate in the both sides of the fetalism with Components Matching, the roll wheel assembly, its roller is laterally set,
It can be rolled in guide base.
A kind of antidote of steel structure bridge sheet panel top element solder deformation, described method includes following steps：
First, groove is opened up according on the tectonic sieving of Slab element to be corrected and the fetalism of Components Matching, with the fetalism of Components Matching
Mouthful；
2nd, Slab element to be corrected is placed on the fetalism with Components Matching, it is put more energy into insertion notch；
3rd, correct roller roller pressure is primarily determined that according to the thickness of Slab element panel to be corrected, the roll-in by 4 ~ 5 times reaches most
Correction eventually；
4th, start operation, make correct roller roll-in on Slab element to be corrected.
Control correct roller on Slab element to be corrected the roll-in speed of service in 500mm ~ 600mm/min.
The present invention designs and produces the fetalism to match with Slab element, Slab element is smoothly placed on fetalism；According to
The thickness of Slab element adjusts the pressure of roll shaft pressure by adjusting block；Correct roller is driven to roll by driving motor, using the side of machinery
Method enable the angular deformation of all sites of Slab element and the rippled edge of Slab element panel just as when correct.
Compared with prior art, the advantage of the invention is that：
The angular deformation of unit and rippled edge shape are all using machinery correction；The angular deformation of Slab element and rippled edge just as when correct；Effect
Rate is high；CO is not discharged to air2Gas；Working condition is improved, reduces the technical requirements to operator.
The method of the present invention by the angular deformation of Slab element and wave transformation it is synchronous, be carried out at the same time correction, correcting welding deformation
During release residual stress, stabilize the size of Slab element component.This correction steel structure bridge thin plate Slab element weldering
Deformation method is connect, the integral planar degree of component is reached requirement, damage caused by avoiding flame straightening, eliminates plate list
The residual stress of meta structure, stabilizes Slab element size, greatly improves the efficiency.
